Solve for x using the

7(x + 3) = -49

Answers

Answer:

x= -10

Step-by-step explanation:

distribute 7 to x and 3: 7x + 21 = -49

subtract 21 from both sides to isolate the variable: 7x= -70

divide both sides by 7 to find x: x= -10

Answer:

X = -10

Step-by-step explanation:

1.- 7x + 21 = -49

Subtract 21 on both sides of the equal sign

You should have:

2.- 7x = -70

Divide 7 on both sides of the equal sign

You should get the answer:

X = -10

:) /

Step-by-step explanation:,,

Answer:

The answer is B:subtract 1,add x,divide by 4

The other answer is D:add x,subtract 1,divide 4

Step-by-step explanation:

when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3

the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=[tex]\frac{3}{4}[/tex]

The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=[tex]\frac{3}{4}[/tex]

With that evidence I can reasonably say that answer to the question is B,and D

what are the steps to solve m -5 - 6m 5

Answers

Answer:

m = -2

Step-by-step explanation:

m - 5 - 6m = 5

First, you need to combine like terms

-6m + m = -5m

-5m - 5 = 5

Next, add 5 to both sides of the equation

-5m - 5 = 5

+ 5 + 5

-5m = 10

Divide -5 by both sides of the equation

-5m = 10

÷-5 ÷-5

m = -2

2x-9x+17=-4
I have a answer but I’m not sure if I’m correct so I just want to double check.

Answers

Answer: x = 3

Step-by-step explanation: Simplify both sides

2x - 9x + 17 = -4

2x + - 9x + 17 = -4

Combine like terms

(2x + -9x) (17) = -4

-7x + 17 = -4

Subtract 17 from both sides

-7x + 17 - 17 = -4 - 17

-7x = -21

Divide both sides by -7

-7x/-7 = -21/-7

x = 3

Answer:

x=3

Step-by-step explanation:

subtract 2x and 9x ( 2x-9x= -7x)subtract 17 and -4 ( -4 -17= -21)divide -21 and -7 ( -21 / -7= -3)x=3

6. Mr. Phuong stayed in a hotel room for 2
nights that cost $210. The hotel room tax
rate in the city is 12%. What is the total cost
for the hotel room? (Example 2)

Answers

Answer:

The total cost of the hotel room is $235.20

Step-by-step explanation:

Here, we want to find the total cost of the hotel room

Total cost of hotel room = Cost of hotel room for the two nights + tax

Tax = 12%

Total cost = 210 + 12% of 210

Total cost = 210 + (12/100 * 210)

Total cost = 210 + 25.2

Total cost = $235.2

Answers

Formula to convert F to C:

(F -32) x 5/9

F = 63 + 10 = 73

73-32 = 41

41 x 5/9 = 22.77777

Rounded to the nearest degree = 23 C

Answer: 63 +10 =73 then you have to round it right

it would be 70 degrees Celsius

Step-by-step explanation:

Thank you ☺️☺️☺️

Answer:

x=30

Step-by-step explanation:

2x+90+x+90+90=360

What is the slope of a line perpendicular to the line whose equation is
2x+12y=−192. Fully reduce your answer.

Answers

Answer:
Mperpendicular=6
Pls mark me brainliest

The slope of a line would be -6 which is perpendicular to the line whose equation is 2x+12y=−192.

What is the slope of the line?

The slope of a line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

We have to determine the slope of a line perpendicular to the line whose equation 2x + 12y = −192.

First, we have to find the slope of the given line

The equation of the line which is given as

2x + 12y = −192

12y = −192 - 2x

Divided by 12 both sides of the above equation to get the slope-intercept form

y = - (1/6)x - 16

Here the slope of the line (m) = -1/6

So the slope of the line perpendicular to the line will be: 1/m = 1/(-1/6) = - 6.

factor 2x^2 - 7x = 0

Answers

Answer: x=3.500

Step-by-step explanation: product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

2x-7 = 0

Add 7 to both sides of the equation :

2x = 7

Divide both sides of the equation by 2:

x = 7/2 = 3.500

A basketball team played five games. In those games, the team won by 7 points, lost by 3, won by 4, lost by 2, and won by 9. What was the mean difference in game scores over the five games?

Answers

Answer:

Step-by-step explanation:

7-3+4-2+9=15

15/5=3

The mean difference in the game scores over the five games is = 5

The points achieved by the various team players =

won by 7, lost by 3, won by 4,lost by 2,won by 9.

To obtain the mean of the points achieved from the five

games the five scores are added together and divided by the number of games which is 5.

That is,

[tex] \frac{7 + 3 + 4 + 2 + 9}{5} [/tex]

Combat Fire, Inc. manufactures steel cylinders and nozzles for two models of fire extinguishers: (1) a home fire extinguisher and (2) a commercial fire extinguisher. The home model is a high-volume (54,000 units), half-gallon cylinder that holds 2 1/2 pounds of multi-purpose dry chemical at 480 PSI. The commercial model is a low-volume (10,200 units), two-gallon cylinder that holds 10 pounds of multi-purpose dry chemical at 390 PSI. Both products require 1.5 hours of direct labor for completion. Therefore, total annual direct labor hours are 96,300 or [1.5 hours (54,000 + 10,200)]. Expected annual manufacturing overhead is $1,570,706. Thus, the predetermined overhead rate is $16.31 or ($1,570,706 96,300) per direct labor hour. The direct materials cost per unit is $18.50 for the home model and $26.50 for the commercial model.
